It should've been GST_TAG_LANGUAGE_CODE, sorry.

Do you get any tags at all though? Like many other things, the
"get-xyz-tags" action signal will most likely only work once you've set
the pipeline to PAUSED or PLAYING state *and* it has prerolled (ie. you
have gotten an ASYNC_DONE message on the pipeline's bus). You need to
wait for it to preroll, you can't just query it right after doing the
_set_state().
